Hi, I was wondering is it best to service an oil boiler in spring, summer, autumn or winter? I know heating engineers may be less busy in the warmer months as they are not being called out to as many emergencies. Also working on a boiler in an unheated garage may be more bearable when its...

If the frost stat is fitted on the internal face of an external wall in a unheated building will it operate as it should? An external wall can get very cold if it is single skin like my garage wall. I thought maybe the cold of the wall would give a colder temp than fitting on an internal...

Thanks agile. Do the probes have to be clamped on the pipe or just pushed on? stu

Thanks chaps. This is going to be for DIY use only. How about a dual input digital thermometer with 2 k type thermocouple probes? Found one for £60. stu

Hi all. I want to get one of these but dont know which one to buy or where from. I will be using it mainly for balancing radiators and getting my flow and return pipe temp differential. May use it for other things too. Or should i be buying clamp on pipe thermometers? Or what else? I...

Thanks noseall. The garage is to the rear of the property about 5M behind and set to the side. Its a long way from the highway and we dont have neighbours on that side, just a farmers field. Infact we only have one neighbour as the house is semi detached with fields all around us. The garages...

Thanks alot everyone. I've much to do with my heating system so i'd better get started. I'm sure you will be hearing plenty from me. I have enjoyed learning about heating systems from here and the web in general - wish i'd become a heating engineer when i was younger! stu

Tony, my concern was the distance between receiver and room stat and the mutiple walls the signal would have to go through - 11M through internal brick wall, double skin exterior wall, across garden and through brick garage wall and all the junk thats in there. stu

It's worcester greenstar heatslave 18/25 condensing combi oil boiler. I think it was the drayton digistat +2 RF instructions which said the receiver should be near the boiler. Cant remember now, it could have been the boiler instructions. Thanks, stu

Thanks Tony. So, i could use the redundant blue wire and take the neutral connection from the junction box where it connects to the fused mains inlet switch? I dont know why the best place for the receiver would be near the boiler. Will a 12M cable have any effect on how the receiver...

Hi. The flat roof on our single detached garage is coming to the end of its life and i am considering putting a proper sloped roof on it - i hate flat roofs and the extra height will be useful for storage. I would be using the exsisting height of the building on one side and building up...

Thanks Mr Hailsham. There is a neutral but it is not used for the current stat. Its only a two wire connection - perm live and switched live. I traced the wires back to the boiler and the blue neutral wire goes to a junction box above the boiler but it is'nt connected to anything. There is...

Hi. I was thinking of replacing our drayton digistat +2 programmable room stat with the wireless version. I want to do this because the stat is in the same room as a wood stove and is playing havoc with the settings. I thought i could remove the digistat from the wall and fit the wireless...

Cheers Ade. I will move the stat soon. Will have to put a junction box in and extend the wire or look into a wireless one. When our last boiler died we thought about going fully wood burning but was put off by the amount of fuel needed and its lack of flexibility. As we did'nt have any...

cheers everyone. i will give your ideas a try stu

It's quiet in here, here, here ,here.................

Thanks for your reply ben. I was hoping i could get them out somehow without taking the rads off. Maybe i'll take them off, drill and use a stud extractor to try get them out. Or maybe i'll just replace all 8 rads as they are all the same! I'll take one off in summer and see. cheers stu

Hi. We have a charnwood country 4 wood burning stove in the kitchen diner. It is the largest room in the house and the output of the stove was considered right by my calculations and those of the Hetas registered installer who put it in. Its an excellent stove but as i use very well...

Hi. A couple of my rads have seized bleed screws. The square heads seem to have been rounded off. To make things worse they are facing the wall so access is limited. I would like to be able to free them up so i can replace them. Any ideas without taking the rad off? Thanks stu.

Thanks for your reply djsarge. Yes frost stat is set at 5 deg C . Pipe stat is set at 20 deg C - is this ok? I realise going against their advice may invalidate the warranty but the advice i was given by worcester ( i pretended to be a qualified installer) was clearly wrong as it did'nt...
